Kaoru is a 17-year-old virgin who has an SM fetish. He secretly dreams about an SM relationship with his childhood friend Nana. One day Kaoru's mom asks Nana to hide all his SM toys so he'll study for a change. However, Nana finds the leather one-piece that Kaoru bought and tries it on, but she accidentally locks it and doesn't have the key! The beginning of their super strange relationship.

Note: The chapter numbers were reset after moving from Young Animal Arashi to Young Animal.

This manga is amazing. I've never before read a manga that was so good at exhibiting the actualities of a BDSM relationship. As such, it's definitely one wild (and exciting ) ride. I love how the story provides plenty of titillating scenes and ideas... surrounded by a solid plot and characters you can actually get to know and care about.

However, there IS one thing I would change about this manga if I could. I believe that the overall scenario and the "breathers" can be equally appealing to men and women who are into BDSM or at least curious/open-minded about it. However... this manga falls prey to the same cliched "Male Lead is an Insufferable Dork" syndrome that every other shounen romance manga has. It's really a shame, because if the male lead was just a normal guy instead of a mega-dork, this could be an amazing powerhouse of a BDSM manga for men AND women.

Don't get me wrong - I still do believe this manga is amazing and one-of-a-kind. It's more than worthy of the "10" I'm rating it. I just wish the sexy bits weren't interrupted by so many "Hey, remember, he's a DORK, guys!" moments.

Well, this work proves how mangakas can deal with OLD taboo subjects like S&M in a such funny and exciting way without using the classic hentai and porn cliches, you can see the "thin" line that the autor put on this work and how that creates a lot of tension between the two main characters, I mean i recommended this manga to some friends who are not even into the manga stuff and they loved it. Amazume artwork just suits the story (tbh he didnt change his style for this particular work). And like many others around here i prefer plump girls

A very enjoyable series, original is almost everything! The main protagonists developing relationship is very interesting to watch, and it's actually based in S&M. I find it amazing how this manga, at least for me, is much more alluring and enticing than real porn. The ecchi it contains is not "Sexual Ecchi", is "Sensual Ecchi". It's also very interesting how the series dismitifies any remaining prejudice against S&M you may have, so much, that it might actually make you get curious about it (that's what happened with me! xD)... wow, now THAT'S an accomplishment!

At first it was pretty interesting (and funny how she accidentaly locks herself in the outfit XD) but i skimed through the 30some chapters that were on a manga site, and i really didnt see much of a storyline, just the girl taking "breathers" and wearing SM getups, and the guy being overjoyed at times.. . . . i read about 4 or 5 chapters, then started the skimming, and it was basically the same thing, and at parts, she looked a bit cross eyed, but i liked that she wasnt stick thin like some manga girls, she was plump but not in a chubby orr fat way. . . but everyone seems to be giving it a 10, so i might give it another chance, but for now -- 3.5/10

I was kinda surprised that the manga was actually based on true SM actions and concepts where master is no a dominant asshole that break the mid of a weak girl, if no a guy that care and exploit the sexual attributes of the female body, a lot of SM authors can learn from this but .... they are lame like rapers only wanna see helpless girls get gangbanged and without own will. The love history is good, the details are great but no too tecnical, gives to pleaple really interest on learn more about true SM.

In my opinion, a sleazy weakling like him, who is 100% opposite of the prince charming type, dominating and making a girl like Nana do anything he says, is what makes this manga interesting and enjoyable. Definately a 10

I am amazed how this series can take a sexual topic, keep the emphasis on the characters, and provide fanservice without getting vulgar. I know everyone has a different definition of vulgar, but this really rides that line between ecchi and vulgar without getting into 'sex'. Perhaps it's just me, but I can empathize with the confusion of the characters as they explore themselves.

Artwork is decent to good. Story is ok, with a couple flashing of brilliance. Characters are more complete than most works near this topic. I don't see the 10's that everyone is giving, but it's definitely a superior manga.

Hot, Sexy, Perverted... I didn't think that a manga could be so enticing. I've read ALOT of H-manga andhave watched ALOT of porn. None have been as alluring and sensuous as Nana to Kaoru. The faces that Nana makes are so debauched that you can ejaculate by just looking at them, and Then Tachi comes along with the raunchiest look ever. I swear, I almost jizzed in my pants. This is a must read.

Too many tens, seriously guys, what's going on? Most of it is typical, what isn't typical showcases the worst of certain tendencies in this genre, and the hentai that usually comes from it. The guy looks extra pathetic, he isn't likeable one bit. The girl likes to be dominated secretly, and they like each other because they knew each other when they were young(cause that's how it works).

I don't like S&M but I'm not knocking it either. This is still meh, but with the added knowledge that it didn't start in a good relationship, with the disturbing hentai mind set.
